' To all whom it may concern:

Be it yknown that I, HERBERT W. WoLFF,'a

citizen of the United States, residing at St.

' Louis, Missouri, have invented a certain new r frming'partbfithisspe and useful Im rovemeiit.- in Door-Q eratinv Mechanism, o which the 4following 1s a full clear, and exact descri tion, such ,as will enable others skilled in the art to which it ap rtainsv tomake and use the same, reference einer-bed ...t0 thelcwmgnyig drawings.

tion, in which-'-u Figure 1 'isa side elevationof a portion of a car provided with in Linfiproved door-operating mechanism. Fig. 2 is a sectional view taken on' the line 2 2 off'F'ig. 1,and Fig. 3 is a detail view showin Vthe -construction of the ca e in which the s vcave is mounted.

" his invention-relates tocars, and particutolduinp ,the contents of the car.

larlyto that t e ofcars-[havingihopper-bottoms.- provide 'with doors whic are openedV "The object. of my invention isto providev a y doorfo ratingmechanism consisting` Vof a novel orm of e ualizing device, and in the preferred `embodiment of my invention saiddevice comprises a-fiexibl'e member connected at itsl en ds to the'doors of .the hopper andv riding freely over a member which 1s moved.

, upwardly to close"the'doors. As said flexi-v .3Q bl emeinber rides freel 'on saidnctuated ,memben any inequality in the .movements of 'iss' winding-s aft.

thefdoors will becoinpen'sated for and both doors ,of the hopper 'will be closed .ositively The member over which theflexible member passespreferablyconsists .of a sheavejthat is connected to one end of an o erating-chain,z whichlma have its' other en fastened to a The manner of connecting the sheave to its operating-,chain also forms one ofthen'ovel' fastening device, thereby reducing the cost of manufacture and enabling a new sheave to be placed .in the cage when .the old one has bef coinegworn or brokenwithfverylittle trouble. v| the-vertical portions' ofthe slots -will actas the Vpreferred form of m invention, 1 designates `built-upv center si 1s, and 2 designates 55* one side of the car to which the outside hopper-sheet 3 is fastened. "lhe inside hoppersheet 4 is connectedto one of thelh center sills, andthe doors 5 for the hop r consist of plates which are strengthene, by angles 6.6:`

and4 7, connected to the sides and e sheets, said doors being-hingedjat,'Svtothe endsheets of the hopper.

--A-In.thenpleelleiiflnbodiment of my iiiveliy tion the car is'providd"with a hopper on 6 5 -ea'ch side of the center sills, and the doors of one hopper are connected to the corresponddoors of the other hopper by vmembers w 'ch I haveherein shown as Z1barsf 9,

of the 4fastened to the-outside'facesof tht:J doors, the 7o said Z- bars being deflected downwardly from points adjacent theirouter ends and brackets or angles 10 'being'provided-for connecting` the same to the inner end portionsfof the v l A flexible chain or cable 11 is connected at its opposite .endsto the intermediate portions of the Z'-bars 9, .and said chain rides'freely over a sheave 12, mounted -in a 'yoke-shav ed.

ycage 13, wliichis connected to one end 0 an 3o operating-chain 14, that passes over arshe'ave 1.5 and is connected to a winding-shaft 1G;

The sheav'e 15 is mounted 'on a shaft 17, car-f.y

ried by the center sills, and the windingeshaft to the center sills,and its end'portionssare mounted in bearings 19, carried by lates),

thatare connected -to the sides o the car.- `At one end of'saidlwinding-shaft is a squared portion to receive alwi'ench or other suitable 9ov actuating device, and said shaft is also fitovided with a ratchet 21, that is engaged'by. a pivotally-mounted pawl 22 for 'prev'cntfii1 1; retrograde movement of said windinglsh'a'lt,

said paw] being carried by a housingfQli, g54

which is connected to the plate 20, andthe paw] being locked in operative position by a pivoiallymounted stop 24., The yokevsha ed cage 13 is provided in its side wall;1

inverted L-s raped. slots 25, and the me wit sheave 12 lis piacedn' said. cage by inserti!!! the.jonrnals thereof into the horizontal pcf tion of the slotsaiid then allowing the sheave to dropdownwardly," so that the botten?L ot -veslefertingto-therawingawhich represent-II bearings for the journals .,o" .the sheayge Vis rotatably mounted in bearings 18, fastened 8 5A I -in its cage Without the aid of a rivet or other vfastening device, thereby reducing the costy Y' doors of'the lioppers connected by members ber to travel over said actuated member,

'doors, a member on which said lexiblemem- 'anism and enabling the sheave to be replaced in case lof breakage or Wear With very little connected, it Will of course be understood When'the sheave is in operative position and the equaliZing-chain v1 1 is ridingo'n the same, it Will beimpossible for sa-id sheave to be displaced; but by removing said chain the sheave can easily be removed from ,its cage.

It Will thus be seen that I have produced a construction in which the sheave is retained of manufacture of the door-operating mechtrouble. As the chain 11 rides freely on the sheave 12, itats as an equalizing device to. i compensate Jfor any inequalities in the movements of the doors and insures both doors-oieach hopper being closed ositively.

' Whilel have herein siown my improved door-operating mechanism as being applied to a car provided with a hopper 'on each side of the center sills ofthe car and having Vthe to Which the ends of the equalizing-chain are substantially as described. p

2. A car provided with a pair of doors, an equalizing device comprising a flexible mem# ber connected at its opposite ends to said V ber rides freely whereby said flexible member ispernntted to travel over said member, and

means for raising said member to'close said doors; substantially as described. I 3. A car provided with a pair ofdoors, a',

flexiblemember .connected to said doors, a sheave on which, said member rides freely, and an actuating member to which said sheave is connected; substantially as described.

4. A. car provided with a pair of doors, a flexible member connected to' said doors, a sheave on which said member is inovably mounted, a chain to which said sheave is connected, and a Windingsliaft to which said chain is connected; substantially as described.

5. A car provided with a pair of doors, a flexible member connected to said doors, a device onwhich said ilexible member rides freely, an actuating 'chain or cable to which` said device is connected, and a sheave over which said' chain passes, substantially as de scribed.

6. A car provided with a pair oi' doors, a flexible member connected to said doors, a sheave on which said fiexible member rides freely, a cage provided with open-endedslots which form bearings for the journals of said sheave, and an actuating-cliain to which said cagel -is connected; vsubstantially vas de scribed.

7. A car provided With liopper's on eaeli side of its center sills, a pairot doors for eacli hopper, transversely-exteiiding members con-L nected to the Corresponding doors ol" each hopper, a iiexible member connected to said transversely-extending members, a 'sheave on which said flexible member rides freely, an. actuating-chain to which said sheave is connected, and a sheave carried by tbe center sills of the car and havingsaidy actuating? chain riding thereon; substantially as described. l A y in testimony whereof l hereunto allix my signature, in the presence of. two witnesses, this 28th day of March, 1906.
